1 in 10,000 ? (100,000 MTBF / 10 hrs)
It's probably more complicated than that, e.g. what happens if it's
already flown for 99,989 hrs and you're flight is the last 10 before
it's service ? I guess they're serviced at 50% of their quoted MTBF
though and a 747 can still fly with one engine lost ?
Not planning a trip are you ?
;-)
Cheers,
